Canadian concert promoter Keystone Entertainment has launched a lawsuit against veteran rock band Aerosmith over a series of cancelled concerts slated for Western Canada last August.

Calgary-based Keystone filed a statement of claim in Alberta Court of Queen's Bench earlier this month, naming the band's members, its corporate entity (Vindaloo Music Inc.), management and agents among the list of defendants.

After frontman Steven Tyler was injured falling off a stage catwalk mid-concert in South Dakota, Aerosmith axed its planned tour — which was to have included stops in Winnipeg, Regina, Edmonton, Calgary and Vancouver — just one day before the first Canadian show.

According to the lawsuit, Keystone's repeated attempts to reschedule the shows were ignored.

Earlier this spring the band announced plans for a new series of European and North American concerts — the Cocked, Locked, Ready to Rock Tour. However, the only Canadian stop will be in Toronto on Aug. 17.

Keystone claims that profits from the Western Canadian Aerosmith dates had been projected to exceed $10 million. The company says the last-minute cancellation left it with a host of expenses — including for promotion and marketing, venue and security permits and equipment rentals.

In February, the Winnipeg Blue Bombers football club launched a lawsuit against Keystone over the cancelled Winnipeg concert. The club claimed it lost more than $97,000 in expenses incurred planning for the show.

Keystone is seeking $6 million in damages.
